EDWIN E. MEISEKOTHEN, OF MADISON, WISCONSIN, ASSIGNQIR FRENCH BATTERY COMPANY, OF 'MADISON, 'WISCO'N'SIN, A CORPORATION "OF WISGONSINQ- DBY-BATTERY CONSTRUCTION.

Application filed April 8, 1925. Serial No. 21,501.

This invention relates particularly to dry battery construction; and the primary objeet is to provide an improved construction whereby dry cells may be cheaplyassembled in a suitable contain er, and adurable battery, having the cells and comiections well insulated, will be afforded.

accordance with the invention, individualcontainers for the dry cells are providech These individual containers are formed n an improved manner, and are nested in :a suitable container. The dry cells are then introduced '=ll1l0 the cell-cavities alf-orded by the individual containers, suitable connections are made between the dry cells, andasealing compound is then poured in to fill the spaces about the cells and the space above the cells.

' The invention is illustrated in its preferred embodimentin the accompanying drawings, in which- Fig. 1 represents a plan View of a battery constructed in accordance with the invenof the dry cells being shown in position and the sealing compound being omitted; Fig. 2, a plan view .of a blank emtion, only a few ploy'ed in forming the individual cell-container; Fig. 3, a perspective view of the eel container formed by folding the blank shown in Fig. 2 Fig. 4, a perspective view of the blank .in partially folded condition; Fig. 5, a broken vertical sectional view taken as indicated at line 5 of Fig. 1; Fig. 6, va plan view of another form of blank employed in forming an individual oell=container; Fig. 7, a perspective view of the blank in partially fold-ed condition; and Fig. 8, a View of the same in completely folded condition.

Tn the construction illustrated, A designates a box-like container which maybe formed of heavy cardboard, if desired; l3 designates individual cell-containers nested in the box A; C, C designates cells housed in the individual containers; and D designates a sealing compound filling the spaces about the dry cells and the space above the dry cells.

In Fig. 2, the individual cell-container B appears in the form of a blank, beforefolding; in Fig.4, the blank is shown partially folded; and in Fig. 3, the blank is shown completely folded, thus forming the individual cellcontainer.

The individual cell-container preferably is formed of light cardboard, or heavy stiif paper. The blank comprises a strip, or rectangular, piece which has its lateral edges out awa or notched, as indicated at l. Slits are cut in the blank along the lines designated 2. Also, the blank is scored longitudi-' na-lly along the two parallel lines 3-3, and also transversely along the two parallel lines designated 4 which intersect the lines .33. The scoring-may be effected by a suitable press operation in such manner that the wings may be readily folded along the -scored lines. Thus, the blank is .dividedint-o the central intermediate section 5 which forms the bottom of the cell-container-; the flankmg intermediate sections 6 and .7 which form two opposed sidewalls of the cell-container;

the wing sections ,8 which flank the section edges ,8 tor the lower ends of the side fla'ps 8 and beveled edges 9 for the .complemental side-flaps .9]. The bevel-s are such that when the flaps. are folded, the edges 8 will reston the edges .9, the end of the folding operation, the side-flaps Flt) will (embrace the side-flaps which comprise the sections 8 and 9. It is preferred to provide one of the sections of the blank, as for example, the free edge of the section 6, with a tab "6", which may be used as a separ-atorbetween the up per edge of the zinc can and thecell connect1on,-or conductor connecting the cells. The blank is shown scored alongthe lineiGP, thus facilitating the bending .over of the tab. The individual cell-.containeis are nested in rows in the box A; the cells are then introduced into the individual containers; and the cells are .then connected by wines, or-conductors, 11, the tabs 6 beingbent overand' interposed between the wires and the upper edges of the zinc cans.

The zinc cans are introduced into the individual cell-containers without any wrap- 100 ping. The cardboard from which the blank If desired, the cells may be introducedinto the individual cellcontainers ,before the;

latter are introduced into the box A.

The .battery completed by pouring in I the" sealing compound Dl which fills the spaces surrounding'the cells and the space above the cells, so that, practicallyspeaking, the cells are imbedded in the sealing compound,

' In Figs. 6-8, B designates a modified form of-1individual cell-container. This container preferably is formed from a rec'-v tangular strip of light cardboard? which is provided with'projections, as shown in Fig. 6.- The piece is scored, or weakened, along parallel lines 12, and along lines perpendicular theretodesignated 13-, 14,15, 16 and 17 The strip is also incised along lines 18,19 and 20.- Thus, the blank comprises the-main sections 21, 22, 23, 24 and 25;"short bottom flaps 26 and 27; longer bottom flaps 28 and 29, and an upper tab 30. 'The'process of folding is indicated in Fig. 7; and the completely folded blank, forming the carton, is

shown in Fig, 8. In foldingthe*blank,'the bottom flap 28 is bent at right anglesto the section22, the sections 21 and 23 are folded so'as to be disposed at right angles to section 22,'the short flaps 26 -and'27 being first bent inwardl so as to overlie the bottom flap 28; the olding is then continued until 1 thesection 24 is brought' to'position oppositethe'section 22, the bottom'fiap 29 being bent inwardly so as to lie beneath the-bot- The foldingis completed by to, overla or emcau'sing the section 25 The parts may be brace, the section 21.

however, this is unscribed can'befo'rmed cheaply,- and avoids Also, such 'a carton provides'for several thicknesses of cardboardat-thebottom of the carton, upon 1 which the cell rests,

which is desirable in certain types of battery assembly: Such a V carton tends to prevent the electrolyte from passing from the'b'ottom of one cel'lto the bottom of another cell.'-
